haplite
Very low (technical/scientific term)Technical/Scientific
Definition
Meaning
A light-colored, fine-grained igneous rock, lacking in darker minerals.
In geology, a leucocratic (light-colored) aplite, typically a granitic rock with a simple mineral composition of quartz and feldspar.
Linguistics
Semantic Notes
Used almost exclusively in petrology (the study of rocks). It is a sub-type classification based on texture and mineralogy. Often contrasted with 'lamprophyre' (dark, rich in mafic minerals).

Examples
By Part of Speech
adjective
British English
- The haplitic dyke cross-cuts the granite.
American English
- Haplitic textures were observed under the microscope.
Examples
By CEFR Level
- The geologist identified a pale, fine-grained rock as haplite.
- The marginal phase of the intrusion transitions from coarse granite to a fine-grained haplite, indicating rapid cooling.
Learning
Memory Aids
Mnemonic
Think of 'HAPLITE' as a 'HAPpy' and 'LITE' rock – it's light in colour and simple in composition.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'гаплит' (a brand name). The Russian geological term is typically 'аплит' or specified as 'светлый аплит'.
Common Mistakes
- Misspelling as 'haplight' or 'haploidite'. Confusing it with the more common 'aplite' without specifying its leucocratic nature.

FAQ
Frequently Asked Questions
No, it is a highly specialized technical term used only in geology and petrology.
It is a light-coloured (leucocratic), fine-grained igneous rock composed primarily of quartz and feldspar.
It would be very unusual and likely not understood outside of a geological context.
'Haplite' is a specific type of 'aplite' that is notably light in colour, emphasizing its lack of dark (mafic) minerals. 'Aplite' is the broader term.
